Automatic detection of un-bolused meals

ABSTRACT

Missed meal bolus reminders or alerts require a user to access the user&#39;s pump and/or remote control to clear the reminder/alert even when the user skipped a meal such that no meal bolus was needed. CGM data can be leveraged such that the missed meal bolus alert is only triggered when glucose levels rise in response to consuming the meal within the programmed time window. Therefore, the alert is only provided when a meal is actually consumed and no bolus has been delivered. This further allows the user to be alerted sooner, i.e., as soon as glucose levels rise a predetermined amount or passed a predetermined threshold indicating consumption of a meal as opposed to only at the end of the programmed window.

RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.16/423,675 filed May 28, 2019, which claims the benefit of U.S.Provisional Application No. 62/677,433 filed May 29, 2018, each of whichis hereby incorporated herein in its entirety by reference.

TECHNICAL FIELD

The present invention is directed to portable infusion pumps and moreparticularly programming for portable infusion pumps.

BACKGROUND

There are many applications in academic, industrial, and medical fieldsthat benefit from devices and methods that are capable of accurately andcontrollably delivering fluids, such as liquids and gases, that have abeneficial effect when administered in known and controlled quantities.Such devices and methods can be particularly useful in the medical fieldwhere treatments for many patients include the administration of a knownamount of a substance at predetermined intervals.

One category of devices for delivering such fluids is that of insulininjecting pumps that have been developed for the administration ofinsulin for those suffering from both type I and type II diabetes. Someinsulin injecting pumps configured as portable infusion devices canprovide continuous subcutaneous insulin injection and/or infusiontherapy for the treatment of diabetes. Such therapy may include theregular and/or continuous injection or infusion of insulin into the skinof a person suffering from diabetes and offer an alternative to multipledaily injections of insulin by an insulin syringe or an insulin pen.Such pumps can be ambulatory/portable infusion pumps that are worn bythe user and may use replaceable cartridges. Such pumps can also delivermedicaments other than or in addition to insulin, such as glucagon,pramlintide, etc. Examples of such pumps and various features that canbe associated with such pumps include those disclosed in U.S. PatentApplication Publication No. 2013/0053816, U.S. Pat. No. 8,573,027, U.S.Pat. No. 8,986,253, U.S. Patent Application Publication No.2013/0324928, U.S. Patent Application Publication No. 2013/0331790, U.S.Pat. No. 8,287,495 and U.S. patent application Ser. No. 15/158,125, eachof which is hereby incorporated herein by reference in its entirety.

Portable infusion pumps for delivering insulin or other medicaments canbe used in conjunction with blood glucose monitoring systems, such asblood glucose meters (BGMs) and continuous glucose monitoring devices(CGMs). A CGM provides a substantially continuous estimated bloodglucose level through a transcutaneous sensor that estimates bloodanalyte levels, such as blood glucose levels, via interrogation of thepatient's interstitial fluid rather than the patient's blood. CGMsystems typically consist of a transcutaneously-placed sensor, atransmitter and a monitor.

Ambulatory infusion pumps typically allow the patient or caregiver toadjust the amount of insulin or other medicament delivered, by a basalrate or a bolus, based on blood glucose data obtained by a BGM or a CGM,and in some cases include the capability to automatically adjust suchmedicament delivery. Some ambulatory infusion pumps may include thecapability to interface with a BGM or CGM such as, e.g., by receivingmeasured or estimated blood glucose levels and automatically adjustingor prompting the user to adjust the level of medicament beingadministered or planned for administration or, in cases of abnormallylow blood glucose readings, reducing or automatically temporarilyceasing or prompting the user temporarily to cease or reduce insulinadministration. These portable pumps may incorporate a BGM or CGM withinthe hardware of the pump or may communicate with a dedicated BGM or CGMvia wired or wireless data communication protocols, directly and/or viaa device such as a smartphone. One example of integration of infusionpumps with CGM devices is described in U.S. Patent Publication No.2014/0276419, which is hereby incorporated by reference herein.

SUMMARY OF THE INVENTION

Missed meal bolus reminders or alerts require a user to access theuser's pump and/or remote control to clear the reminder/alert even whenthe user skipped a meal such that no meal bolus was needed. CGM data canbe leveraged such that the missed meal bolus alert is only triggeredwhen glucose levels rise in response to consuming the meal within theprogrammed time window. Therefore, the alert is only provided when ameal is actually consumed and no bolus has been delivered. This furtherallows the user to be alerted sooner, i.e., as soon as glucose levelsrise a predetermined amount or passed a predetermined thresholdindicating consumption of a meal as opposed to only at the end of theprogrammed window.

In an embodiment, an ambulatory infusion pump system can include a pumpmechanism configured to facilitate delivery of a medicament to apatient, a memory adapted to store parameters relating to delivery ofthe medicament, a communications device adapted to receive informationfrom a continuous glucose monitoring system and a processor functionallylinked to the pump mechanism, the memory and the communications device.The processor can be configured to store in the memory a missed mealbolus alarm defining a time period during which a meal is expected to beconsumed and provide a reminder to the user to deliver a meal bolus ifno meal bolus is delivered by the pump mechanism during the time period.At the beginning of the time period, the processor can monitor CGM datafor the user from the continuous glucose monitoring system and comparethe CGM data to a threshold relating to glucose levels. The processorcan provide the reminder to the user to deliver the meal bolus only ifthe CGM data exceeds the threshold (indicating consumption of a meal)and no meal bolus has been delivered by the pump mechanism.

FIGS. 3A-3B depict another pump system including a pump 102 that can beused with embodiments. Drive unit 118 of pump 102 includes a drivemechanism 122 that mates with a recess in disposable cartridge 116 ofpump 102 to attach the cartridge 116 to the drive unit 118. Pump system100 can further include an infusion set 145 having a connector 154 thatconnects to a connector 152 attached to pump 102 with tubing 153. Tubing144 extends to a site connector 146 that can attach or be pre-connectedto a cannula and/or infusion needle that punctures the patient's skin atthe infusion site to deliver medicament from the pump 102 to the patientvia infusion set 145.

In one embodiment, pump 102 includes a processor that controlsoperations of the pump and, in some embodiments, may receive commandsfrom a separate device for control of operations of the pump. Such aseparate device can include, for example, a dedicated remote control ora smartphone or other consumer electronic device executing anapplication configured to enable the device to transmit operatingcommands to the processor of pump 102. In some embodiments, processorcan also transmit information to one or more separate devices, such asinformation pertaining to device parameters, alarms, reminders, pumpstatus, etc. In one embodiment pump 102 does not include a display butmay include one or more indicator lights 174 and/or one or more inputbuttons 172. Pump 102 can also incorporate any or all of the featuresdescribed with respect to pump 12 in FIG. 2. Further details regardingsuch pumps can be found in U.S. Pat. No. 10,279,106 and U.S. PatentPublication Nos. 2016/0339172 and 2017/0049957, each of which is herebyincorporated herein by reference in its entirety.

Pump 12 or 102 can interface directly or indirectly (via, e.g., asmartphone or other device) with a glucose meter, such as a bloodglucose meter (BGM) or a continuous glucose monitor (CGM). Referring toFIG. 4, an exemplary CGM system 100 according to an embodiment of thepresent invention is shown (other CGM systems can be used). Theillustrated CGM system includes a sensor 101 affixed to a patient 104that can be associated with the insulin infusion device in a CGM-pumpsystem. The sensor 101 includes a sensor probe 106 configured to beinserted to a point below the dermal layer (skin) of the patient 104.The sensor probe 106 is therefore exposed to the patient's interstitialfluid or plasma beneath the skin and reacts with that interstitial fluidto produce a signal that can be associated with the patient's bloodglucose (BG) level. The sensor 101 includes a sensor body 108 thattransmits data associated with the interstitial fluid to which thesensor probe 106 is exposed. The data may be transmitted from the sensor101 to the glucose monitoring system receiver 100 via a wirelesstransmitter, such as a near field communication (NFC) radio frequency(RF) transmitter or a transmitter operating according to a “Wi-Fi” orBluetooth® protocol, Bluetooth® low energy protocol or the like, or thedata may be transmitted via a wire connector from the sensor 101 to themonitoring system 100. Transmission of sensor data to the glucosemonitoring system receiver by wireless or wired connection isrepresented in FIG. 4 by the arrow line 112. Further detail regardingsuch systems and definitions of related terms can be found in, e.g.,U.S. Pat. Nos. 8,311,749, 7,711,402 and 7,497,827, each of which ishereby incorporated by reference in its entirety.

In an embodiment of a pump-CGM system having a pump 12, 102 thatcommunicates with a CGM and that integrates CGM data and pump data asdescribed herein, the CGM can automatically transmit the glucose data tothe pump. The pump can then automatically determine therapy parametersand deliver medicament based on the data. Such an automatic pump-CGMsystem for insulin delivery can be referred to as an artificial pancreassystem that provides closed-loop therapy to the patient to approximateor even mimic the natural functions of a healthy pancreas. In such asystem, insulin doses are calculated based on the CGM readings (that mayor may not be automatically transmitted to the pump) and areautomatically delivered to the patient at least in part based on the CGMreading(s).

For example, if the CGM indicates that the user has a high blood glucoselevel or hyperglycemia, the system can automatically calculate aninsulin dose necessary to reduce the user's blood glucose level below athreshold level or to a target level and automatically deliver the dose.Alternatively, the system can automatically suggest a change in therapyupon receiving the CGM data such as an increased insulin basal rate ordelivery of a bolus, but can require the user to accept the suggestedchange prior to delivery rather than automatically delivering thetherapy adjustments.

If the CGM data indicates that the user has a low blood glucose level orhypoglycemia, the system can, for example, automatically reduce a basalrate, suggest to the user to reduce a basal rate, automatically deliveror suggest that the user initiate the delivery of an amount of asubstance such as, e.g., a hormone (glucagon) to raise the concentrationof glucose in the blood, automatically suggest that the user, e.g.,ingest carbohydrates and/or take other actions and/or make othersuggestions as may be appropriate to address the hypoglycemic condition,singly or in any desired combination or sequence. Such determination canbe made by the infusion pump providing therapy or by a separate devicethat transmits therapy parameters to the infusion pump. In someembodiments, multiple medicaments can be employed in such a system as,for example, a first medicament, e.g., insulin, that lowers bloodglucose levels and a second medicament, e.g., glucagon, that raisesblood glucose levels.

As with other parameters related to therapy, such thresholds and targetvalues can be stored in memory located in the pump or, if not located inthe pump, stored in a separate location and accessible by the pumpprocessor (e.g., “cloud” storage, a smartphone, a CGM, a dedicatedcontroller, a computer, etc., any of which is accessible via a networkconnection). The pump processor can periodically and/or continuallyexecute instructions for a checking function that accesses these data inmemory, compares them with data received from the CGM and actsaccordingly to adjust therapy. In further embodiments, rather than thepump determining the therapy parameters, the parameters can bedetermined by a separate device and transmitted to the pump forexecution. In such embodiments, a separate device such as the CGM or adevice in communication with the CGM, such as, for example, asmartphone, dedicated controller, electronic tablet, computer, etc. caninclude a processor programmed to calculate therapy parameters based onthe CGM data that then instruct the pump to provide therapy according tothe calculated parameters.

As is known in the art, a meal bolus alarm is an alarm that reminds theuser to deliver a meal bolus during a predetermined time interval. Forexample, if the user typically eats breakfast between 7:00 am and 8:00am, the user may set a missed meal bolus alarm/reminder for an intervalbetween, e.g., 6:15 am and 8:00 am. In this example, an alarm sounds ifa meal bolus is not delivered within this interval. Generally, the usercan navigate the menu structure of an infusion pump and/or remotecontrol for an infusion pump to a Missed Meal Bolus Reminder or Alarmsetting. From there, the user can select a start time and an end timedefining a period of time during which a meal is expected to be consumedfor a reminder that is then stored in memory and can be turned on andoff and/or set to be active on certain days. If the reminder or alarm isturned on and/or active on a given day, the pump and/or remote willdetect whether or not a meal bolus was programmed and/or deliveredduring the programmed period of time. If a meal bolus is delivered, thenthe pump takes no further action. However, if no meal bolus is deliveredby the programmed end time, the pump will automatically issue a missedmeal bolus alarm reminder or alert to remind the user to deliver a mealbolus responsive to the expected meal. Further details regarding missedmeal bolus alarms/reminders can be found in U.S. Pat. No. 8,690,856,which is hereby incorporated by reference herein in its entirety.

Existing infusion pumps therefore can be programmed to alert the user ifno bolus is given during a specified time window, but do soautomatically if no bolus is delivered without detecting if the patientactually ate a meal such that the bolus is actually required. Forexample, a user may at times skip a usual meal for which a missed bolusalarm or reminder is programmed such that the alarm/reminder is notnecessary. With missed meal bolus reminders or alerts as describedabove, the reminder/alert requiring the user to access the user's pumpand/or remote control and clear the reminder/alert even when the userskipped a meal is an unnecessary hassle. Embodiments described hereinseek to address this issue by leveraging CGM data such that the missedmeal bolus alert is only triggered when glucose levels rise in responseto consuming the meal within the programmed time window. Therefore, thealert is only provided when a meal is actually consumed and no bolus hasbeen delivered. This further allows the user to be alerted sooner, i.e.,as soon as glucose levels rise a predetermined amount or passed apredetermined threshold indicating consumption of a meal as opposed toonly at the end of the programmed window.

In one embodiment, software resident on the pump and/or a device forremotely controlling the pump reads and/or records the glucoselevel/status from the CGM at the start of the programmed meal window.During the meal window, the software continuously or periodically checksif the glucose level has risen by more than a certain threshold abovethe starting level. The threshold can be, for example, an amount abovethe starting level, a percentage above the starting level and/or apredetermined high glucose level threshold. In various embodiments, thedetection threshold could be fixed, selected from a limited list ofoptions, or completely user specified.

The software alerts with a missed bolus alarm/reminder only if theglucose level has risen above the threshold and no bolus has beenadministered during the meal window. In various embodiments, thesoftware can provide the alert when the threshold is reached before theend of the programmed time period or can be delayed until the end of thetime period even after reaching the threshold in order to enable to userto still deliver the bolus within the programmed window. If thethreshold has not been reached by the end of the programmed missed mealbolus window, the missed meal bolus alert/reminder is not provided tothe user. This effectively provides an automatic cancellation of themissed meal bolus alarm based on the CGM data indicating no meal wasconsumed, which saves the user the inconvenience of having to address anunneeded alert.

In various embodiments, the software can utilize other statisticalmeasures alternatively and/or in addition to glucose level. For example,the software can analyze the glucose rate (e.g., in mg/dL/min) duringthe meal window and alert only when the glucose rate is above athreshold and/or analyze the change in glucose rate during the mealwindow and alert only when the glucose rate changes by a threshold.

FIG. 5 depicts an embodiment of a method 200 of providing diabetestherapy that includes detecting un-bolused meals and modifying missedmeal bolus alarms according to an embodiment. At step 202 programmingfor a missed meal bolus alarm for an infusion pump is received andstored. In embodiments, the alarm input can be received via a userinterface of and stored via a memory of the infusion pump, a remotecontrol device, etc. The method continues at step 204 when the beginningtime for the programmed alarm is reached on a day for which theprogrammed alarm is turned on/active.

During the programmed time window, the system monitors both whether ornot a meal bolus is delivered with the pump at step 206 and the CGM datafor the user at step 208. At step 210, the system determines if a mealbolus has been delivered with the pump. If so, at step 212 the missedmeal bolus alarm is cancelled and no alarm is issued because a boluscorresponding to the scheduled meal was delivered. When no meal bolushas been delivered, the system at step 214 continually monitors the CGMdata to determine if the CGM alarm threshold has been reached. If theCGM alarm threshold is reached and no meal bolus has been delivered, themissed meal bolus alarm is issued at step 216. This can be done, forexample, at the time the threshold is reached as indicated by the solidarrow in FIG. 5 or only after the programmed end time of the alarmwindow is reached at step 218 without a meal bolus being delivered asindicated by the dashed arrows in FIG. 5. If the CGM alarm threshold isnot reached when the alarm window ends at step 218, the system revertsto step 212 and no missed meal bolus alarm is issued because the systemhas determined from the CGM data that no meal was consumed. As notedabove, method 200 saves a user from the hassle and inconvenience ofresponding to unnecessary missed meal bolus alarms when no meal wasconsumed during a programmed meal window.

In embodiments, the software can further automatically disable themissed meal bolus reminder if the glucose level goes below a lowthreshold and/or is dropping at a rate greater than a threshold. Forexample, if a user's glucose level is low, the carbohydrates consumedduring the meal window may be needed to bring the user's glucose levelup to a safer level and delivery of a meal bolus may drop the user'sglucose level to a dangerously low level. By disabling the bolusreminder when a user's glucose level is below a certain predeterminedthreshold, delivery of such an unneeded bolus can be deterred.

Although primarily described herein with respect to a processor of aninfusion pump in communication with a CGM, it should be understood thatsome or all of the steps of the methods described herein can beperformed by a processor of a remote control device including, forexample, a consumer electronic device such as a smartphone or adedicated remote controller, in communication with a CGM. For example,the remote control device may receive and store the missed meal bolusalarm, communicate with the CGM to receive CGM data and determinewhether or not the missed meal bolus alarm should be issued. Such remotecontrol device may communicate with the pump to determine if a bolus wasdelivered with the pump and/or the device may inherently know whether ornot a bolus has been delivered by receiving the bolus programming at theremote control device and issuing an operating command to the pump todeliver the bolus.

Although the embodiments herein are specifically described with respectto the delivery of insulin, delivery of other medicaments, singly or incombination with one another or with insulin, including, for example,glucagon, pramlintide, etc., as well as other applications are alsocontemplated. Device and method embodiments discussed herein may be usedfor pain medication, chemotherapy, iron chelation, immunoglobulintreatment, dextrose or saline IV delivery, treatment of variousconditions including, e.g., pulmonary hypertension, or any othersuitable indication or application. Non-medical applications are alsocontemplated.
